Description

AT 401 587 BAT 401 587 B

Die Erfindung bezieht sich auf eine Anzeigevorrichtung mit einem Rasterkörper, in dem eine Mehrzahl von Reflektoren ausgebildet ist, in denen eine elektrisch erregbare Lichtquelle angeordnet ist, wobei jeder Reflektor durch eine linsenförmige Streuscheibe abgedeckt ist.The invention relates to a display device with a grid body, in which a plurality of reflectors is formed, in which an electrically excitable light source is arranged, each reflector being covered by a lenticular lens.

Bei einer aus der DE 29 32 413 A1 bekannten Anzeigevorrichtung dieser Art wird die Rasterung durch gleichmäßig nebeneinander angeordnete runde Reflektoren gebildet, die mit je einer Lichtquelle versehen sind. Die nach Art von Rückstrahlern ausgebildeten Streuscheiben sind in einem plattenartigen Bauteil angeordnet, der mit seinen Rändern den Rasterkörper übergreift.In a display device of this type known from DE 29 32 413 A1, the grid is formed by round reflectors which are arranged uniformly next to one another and are each provided with a light source. The diffusers designed in the manner of reflectors are arranged in a plate-like component which overlaps the grid body with its edges.

Dadurch ergeben sich einerseits verhältnismäßig große Stärken der Anzeigevorrichtung, anderseits überstrahlen die einzelnen Streuscheiben einander, wodurch keine exakte Anzeige entsteht.This results in relatively large strengths of the display device on the one hand, and on the other hand the individual diffusing screens outshine one another, as a result of which no exact display is produced.

Die Erfindung hat es sich insbesondere zum Ziel gesetzt, eine Anzeigevorrichtung zu schaffen, die bei gegebener Größe eine geringere Stärke als die bekannten Anzeigevorrichtungen aufweisen kann und bei der die angezeigten Zeichengruppen besser lesbar sind. Erreicht wird dies dadurch, daß jeder Reflektor an seinem der Lichtquelle gegenüber liegenden Ende eine lichtdichte Fassung für die einzelnen Streuscheiben aufweist.In particular, the invention has set itself the goal of providing a display device which, given a size, can have a lesser strength than the known display devices and in which the displayed character groups are easier to read. This is achieved in that each reflector has at its end opposite the light source a light-tight socket for the individual lenses.

Bei einer bevorzugten Ausführungsform der Erfindung wird die Rasterung des Rasterkörpers durch Rechtecke, vorzugsweise Quadrate gebildet, deren jedes durch mindestens eine Diagonale in Dreiecke geteilt wird, wobei jedes Dreieck das durch eine Streuscheibe abgedeckte Ende eines mit einer Lichtquelle versehenen Reflektors bildet.In a preferred embodiment of the invention, the rasterization of the raster body is formed by rectangles, preferably squares, each of which is divided into triangles by at least one diagonal, each triangle forming the end of a reflector provided with a light source and covered by a diffusing screen.

Die Lesbarkeit der angezeigten Zeichengruppen wird dadurch gesteigert, daß die Streuscheiben eine zur Lichtquelle weisende linsenförmige Wölbung besitzen.The legibility of the displayed groups of characters is increased in that the lenses have a lenticular curvature facing the light source.

Um eine mehrfarbige Anzeige zu erreichen, können die Lichtquellen und/oder Streuscheiben verschie-denfärbig ausgebildet sein.In order to achieve a multi-colored display, the light sources and / or diffusing screens can be designed in different colors.

Nachstehend ist die Erfindung anhand von in den Zeichnungen dargestellten Ausführungsbeispielen beschrieben. Dabei zeigen: Fig. 1 eine Draufsicht auf eine erfindungsgemäße Anzeigevorrichtung: Fig. 2 eine schaubildliche Darstellung der Anzeigevorrichtung nach Fig. 1 mit auseinander gezogenen Einzelteilen: Fig. 3 eine vergrößerte Darstellung eines Teiles der Anzeigevorrichtung nach Fig. 1; Fig. 4 einen Schnitt nach der Linie IV-IV in Fig. 3; Fig. 5 als Beispiel eine Anzeige mit einer bisher üblichen Anzeigevorrichtung: Fig. 6 eine Anzeige mit einer erfindungsgemäßen Anzeigevorrichtung unter Verwendung einer Proportionalschrift; Fig. 7 in einer der Fig. 3 ähnlichen Darstellung eine weitere Ausführungsform der Erfindung.The invention is described below with reference to exemplary embodiments shown in the drawings. 1 shows a plan view of a display device according to the invention: FIG. 2 shows a diagrammatic representation of the display device according to FIG. 1 with individual parts pulled apart: FIG. 3 shows an enlarged representation of a part of the display device according to FIG. 1; 4 shows a section along the line IV-IV in Fig. 3. 5 shows, as an example, a display with a previously common display device: FIG. 6 shows a display with a display device according to the invention using a proportional font; 7 shows a further embodiment of the invention in a representation similar to FIG. 3.

Gemäß den Fig. 1 bis 4 besteht eine Anzeigevorrichtung im wesentlichen aus einem Rasterkörper 1, Lichtquellen 2, die auf einer Vorrichtung 3 zur Zufuhr von elektrischem Strom, z.B. einer Printplatte befestigt sind, und linsenförmigen Streuscheiben 4. Die Rastetung des Rasterkörpers 1 wird im gezeichneten Ausführungsbeispiel durch Quadrate gebildet, deren jedes durch zwei Diagonalen in vier Dreiecke geteilt wird. Es entstehen dadurch in Draufsicht dreieckförmige Gebilde, deren sich nach innen zu erstreckende Wände als pyramidenförmige Reflektoren 5 ausgebildet sind, wobei im Bereich der jeweiligen Pyramidenspitze je eine Lichtquelle 2 sitzt.1 to 4, a display device consists essentially of a grid body 1, light sources 2, which are mounted on a device 3 for supplying electrical current, e.g. are attached to a printed circuit board, and lenticular lenses 4. In the exemplary embodiment shown, the latching of the raster body 1 is formed by squares, each of which is divided into four triangles by two diagonals. This results in a top view of triangular structures, the inwardly extending walls of which are formed as pyramid-shaped reflectors 5, one light source 2 each being located in the region of the respective pyramid tip.

An seinem der Lichtquelle 2 gegenüber liegenden Ende bildet jeder Reflektor 5 eine lichtdichte Fassung 6 für die jeweilige Streuscheibe 4.At its end opposite the light source 2, each reflector 5 forms a light-tight socket 6 for the respective lens 4.

Die Streuscheiben 4 sind in den Rasterkörper 1, bzw. in die jeweils vorgesehenen Fassungen 6 eingepreßt. Die die Fassungen bildenden, dünnen, etwa 0,5 mm starken lichtdichten Stege zwischen den angrenzenden Streuscheiben 4 verhindern die Überstrahlung der Streuscheiben an den Kanten. Für eine gleichmäßige Lichtverteilung sind die Streuscheiben 4 an ihren zu den Lichtquellen 2 weisenden Flächen mit linsenförmigen Wölbungen 7 versehen.The lenses 4 are pressed into the grid body 1 or in the respective sockets 6 provided. The thin, approximately 0.5 mm thick light-tight webs forming the sockets between the adjacent diffusing disks 4 prevent the diffusing disks from overexposing at the edges. For a uniform light distribution, the lenses 4 are provided with lenticular curvatures 7 on their surfaces facing the light sources 2.

Durch die erfindungsgemäße Ausbildung wird ein „LCD-Effekt" erreicht, ohne daß die Nachteile der üblichen LCD-Anzeigen auftreten. Die Aufteilung einer in den Abmaßen frei wählbaren Schriftfläche in viele Rasterpunkte ermöglicht die Darstellung aller Schriftzeichen und auch die Darstellung von Laufschriften ist möglich. Als weiterer wesentlicher Vorteil des erfindungsgemäßen Systems ist die Möglichkeit der freien Beschriftung über die komplette Schriftfläche (z.B. zehn Zeichen 200 mm hoch oder zwei Zeilen mit mindestens zwanzig Zeichen 90 mm hoch) hervorzuheben. Auch Proportionalschriften sind darstellbar, wie anhand der Fig. 6 gezeigt wird.Due to the inventive design, an "LCD effect" achieved without the disadvantages of the usual LCD displays. The division of a freely selectable writing surface into many grid points enables the display of all characters and the display of tickers is also possible. Another important advantage of the system according to the invention is the possibility of free labeling over the entire writing surface (e.g. ten characters 200 mm high or two lines with at least twenty characters 90 mm high). Proportional fonts can also be represented, as is shown with reference to FIG. 6.

Bei einem Vergleich der Fig. 5 und Fig. 6 ergibt sich der Vorteil der erfindungsgemäßen Anordnung gegenüber der bisher üblichen LCD-Technik. Fig. 5 zeigt die bisher übliche Aufteilung von LCD-Gläsern mit den für die Leiterbahnen notwendigen Mittelstegen. Demgegenüber ist in Fig. 6 eine erfindungsgemäße Anzeige dargestellt, wobei eine Proportionalschrift verwendet werden kann.A comparison of FIGS. 5 and 6 shows the advantage of the arrangement according to the invention over the LCD technology which has been customary to date. Fig. 5 shows the previously common division of LCD glasses with the central webs necessary for the conductor tracks. In contrast, a display according to the invention is shown in FIG. 6, wherein a proportional font can be used.

In Fig. 7 ist ein weiteres Ausführungsbeispiel der Erfindung dargestellt, wobei die Quadrate nur durch eine Diagonale in zwei Dreiecke unterteilt sind und in dem entstandenen pyramidenförmigen Reflektor drei Lichtquellen 21, 22 und 23 angeordnet sind, die verschiedenfarbig ausgebildet sein können. 27 shows a further exemplary embodiment of the invention, the squares being divided into two triangles only by a diagonal and three light sources 21, 22 and 23 being arranged in the resulting pyramid-shaped reflector, which may be of different colors. 2nd
